SINGAPORE, April 24 (Reuters) - Industrial metals in Shanghai decreased on Wednesday following declines in London overnight and amid fears that China may ease its economic stimulus.
The most active copper contract in Shanghai ended down 0.4 percent to 48,960 yuan ($7,282.25) a tonne, while aluminium fell 0.4 percent, nickel closed down 1 percent and zinc dropped 1.8 percent.
"Overnight, the London metals were not doing well. In the Shanghai Futures Exchange, there's also some selloff pressure, mainly because of the possibility that China may scale back its monetary easing," said analyst Helen Lau of Argonaut Securities.
Lau said investors will look to China's April purchasing managers index (PMI), due next week, to see whether China's economy is indeed rebounding, following a strong figure in March.
"If the April number can be very good on its own, that will definitely improve market sentiment," Lau said.
In London, metals had won some support from progress in U.S.-China trade talks, but gains were capped by a stronger U.S. dollar, which was steady on Wednesday after rising to a 22-month high overnight.
A stronger dollar makes dollar-denominated metals more expensive for countries using other currencies to import.
